March 21, 201610 yr Hi ... just upped to 6.1.9 from 5.0.6 and i'm seeing a redline in my syslog .... 'Mar 21 14:13:54 Tower sshd[1308]: Server listening on 0.0.0.0 port 22' Anyone able to interpret this for me?
March 21, 201610 yr 0.0.0.0 means that an IP address hasn't yet been assigned to your Ethernet device. Not quite true. 0.0.0.0 means that the ssh daemon is listening on port 22 for every network interface. It's precise behaviour is configured by the /etc/ssh/sshd_config file where the ListenAddress parameter modifies its scope. E.g ListenAddress 192.168.1.100 makes it listen on that specific address only. It isn't red (as in 'Error'). It's orange (as in 'Login'), and is actually a false positive.
March 21, 201610 yr Author So i can ignore it then, yes? And yes ... i switched off everything bar 'login' filter and it is exactly that, you're quite correct although it still looks red to me
March 21, 201610 yr Yes, indeed. It's quite normal. Here it is in the syslogs of two of my servers, the first running unRAID 6.2.0-beta19 and the second running unRAID 6.1.19: Mar 18 22:12:50 Lapulapu rpc.statd[1499]: Initializing NSM state Mar 18 22:12:50 Lapulapu sshd[1518]: Server listening on 0.0.0.0 port 22.

March 21, 201610 yr 0.0.0.0 means that an IP address hasn't yet been assigned to your Ethernet device. Not quite true. 0.0.0.0 means that the ssh daemon is listening on port 22 for every network interface. It's precise behaviour is configured by the /etc/ssh/sshd_config file where the ListenAddress parameter modifies its scope. E.g ListenAddress 192.168.1.100 makes it listen on that specific address only. It isn't red (as in 'Error'). It's orange (as in 'Login'), and is actually a false positive. Login related messages in the syslog do not indicate necessarily an error condition, but are highlighted to give the user an immediate glance on login related activities, e.g. to see who and when have been logged in. As noted by John_M, the default port of SSH is 22, and login is accepted on any interface of the server (0.0.0.0). This is the standard setting in all 6.x versions of unRAID.
